Transition to Superparamagnetism of Diamagnetic Nanoparticles

RAJAPALAIYAM, India - Feb. 25, 2014 - PRLog -- Magnetic nanoparticles Researchers from worldwide believe that Superparamagnetism is a form of magnetism, which appears only in small ferromagnetic or ferrimagnetic nanoparticles but contrast to this concept Superparamagnetism has been discovered in diamagnetic nanoparticles. The researcher Ms.Theivasanthi (PACR Polytechnic College, Rajapalayam, India) who has discovered this breakthrough advancement comments: Invention of room temperature Superparamagnetism in diamagnetic nanoparticles is another milestone in nanoparticles / superparamagnetism research activities and it will lead to new concept in magnetic research. Recently, VSM analysis of the sample nanomaterial (diamagnetic) has been done at IIT Madras (India). The preliminary research result / figure confirm superparamagnetic behavior. Further research on this issue is undergoing.

The said researcher and M.Alagar (Ayya Nadar Janaki Ammal College, India) have already explored superparamagnetic behavior of Lead nanoparticles which is also a diamagnetic material. Their research article has been published in

She also explained that superparamagnetic nanoparticles have many applications storage devices i.e. hard disk drives, Ferrofluid, Biomedical applications like Contrast agents in Magnetic Resonance Imaging (MRI), Magnetic separation, targeted drug delivery, hyperthermia of cancer etc.
